I have a Slimline Bosch dishwasher that will not empty. I have cleaned the bottom of the dishwasher out and removed the cover for the impeller. I have removed the discharge pipe to see if there is any debris in there and cleared that out too. It will still not empty. I reckon it could either be a water level sensor or the pump (any other ideas would be welcomed). I have taken the unit apart but can't seem to get the the pump in the base of the unit and I don't know if there is a water level sensor (or where to find it) Could anyone advise on how to remove the base of the unit so I can get to the pump and let me know if/where the water level sensor is? Thanks in advance
